PEBI'ORATING MACHINE.

Application filed May 29, 1925. Serial No. 38,795.

This invention relates to a machine for ornamenting shoe uppers, or parts thereof, by cutting out small portions of the material to form orifices therein, the machine including a reciprocating platen and a group of punches supported in the path of the platen and adapted to cooperate therewith in cutting out portions of the material of a shoe upper interposed between the punches and the platen.

The chief object of the invention is to provide a perforating machine adapted to be advantageously operated to perforate the several parts of a fitted upper, after said parts have been assembled and stitched together.

A machine embodying the invention includes an anvil supporting the usual punches, in position to cooperate with the platen, and movable on a fixed supporting bed crosswise of the path of the platen to locate the punches under various parts of the plunger, and to permit the withdrawal of the punches from the path of the plunger.

The anvil is provided with a guide element centrally located between oppositelatcral sides of the anvil, and the sup orting bed is provided with a complementa guide element, centrally located between opposite lateral edges of the bed and between the lateral sides of the anvil. The arrangement of said guide elements is such that anvils of different sizes and shapes may be used interchangeably on the same bed, Without change or adaptation of either of the guide elements, said elements bein medially arranged relative to the sides 0% the anvil and the edges of the bed, so that hands grasping the work at opposite sides of the anvil are not obstructed by the guide elements. The machine frame and the anvil are so formed that the operators hands, while located below and out of the path of the plunger and below the top of the anvil and the punches thereon, may grasp marginal ortlons of the upper and hold the latter in t 1e different positions relative to the platen and the punches, required to cause the perforation of different parts of a fitted upper by a series of operations,the operators hands being so located that they are not liable to be injured during the punching operation, and are freely movable to hold the grasped marginal portions of the upper in the different positions required.

Other objects of the invention, and means for accompl1shing the same, will appear hegzpialfter.

Figure 3 is a section on line 3-3 of Figure 1.

Figure 4 is a side elevation, showing'the machine on a smaller scale, and an adfunct hereinafter described, associated therewith.

Figure 5 shows in perspective the adjunct shown by Figure 4. v

Figure 6 is a fragmentary section on line 66 of Figure 5.

Figure 7 is a fragmentary section on line 7--'i' of Figure 6.

The same reference characters indicate the same parts in all of the figures.

The frame of the machine designated as a whole by 12, is provided with guides in which a reciprocating platen 13 is movable.

The guides here shown include fixed plates or gibs 14 (Figure 13, and the plunger is fixeccll to a slide or hea 15, engaged with the gm es.

Extending under the platen is a fixed bed, arranged in a plane substantially at right angles with the path of the platen. The bed may include an inner portion 16, integral with the frame. and an outer ortion 16, formed as a shelf or bracket, xed to the frame as shown by Figure 3.

Movable on the bed is an anvil 17, to the upper or head portion of which is detachably secured a block or plate 18, carying the usual tubular or hollow punches 19, adapted to cooperate with the platen in cutting orifices in an upper, the form and arrangement of the orifices being determined by the form and arangement of the punches. The block also carries the usual yielding stripper plate 20, adapted to' be depressed by the platen and to strip the work from the punches when the platen rises. It will be understood that there is nothing new with me in the punching and stripping means, and that blocks 18 of various sizes and having various forms and arrangements of punches may be used interchangeably.

The bed and the anvil are provided with complemental guide elements, medially arranged relative to opposite lateral edges of the bed, and opposite lateral sides of the anvil, and adapted and arranged to gulde the anvil in a path parallel with the bed and substantially at right angles with the path of the platen, the preferred guide elements being a rib or track 21, fixed to and centrally arranged on the bed, between the opposite edges thereof, and extending from the outer to the inner end thereof, and a groove 22, formed in the base portion of the anvil between opposite sides thereof and havin a sliding fit on the track 21 The centre or medial location of said gu de elements midway between the lateral sides of the anvil and the lateral edges of the bed ensures an equal bearing of the anvil on the bed at each side of the guide elements, as shown by Figures 1 and 2, and enables anvils of different widths to be used interchangeably, so that a relatively narrow anvil may be used as shown by Figure 1, and a wider anvil as shown by Figure 2. The medial location of the guide elements also prevents interference of said guide elements with hands grasping the work, the guide elements being internally arranged so that they do not obstruct spaces for the hands at opposite sides of the anvil.

The frame is preferably formed with a recess, designated by the numeral 23 in Figures 1 and 2, formed to receive the anvil, and of such size that spaces are formed at opposite sides of the anvil in which the hands it of the operator may be inserted, as indicated by dotted lines in Figure 1, said spaces permitting the location of the hands below the top of the anvil, while marginal portions of an upper extending across the punches are grasped by the hands. This location of the hands prevents liability of injurythereto by the punching and stripping means. and by the platen during the operation of the machine.

To additionally guard against such injury, I provide hand guards 24. overhanging the spaces at opposite sides of the anvil, as shown by Figure 1. and preferably composed of metal plates having shanks 25, adjustably secured by set screws 26 to a transverse rod 27. Said rod is secured by set screws 28 to fixed ears 29 (Figure 1) on the frame. The hand guards are adjustable on the rod, to conform to the width of the anvil, as indicated by Figures 1 and 2. The guards render it impossible for the operator to insort a finger between the stripper plate and the platen.

It will now be seen that a fitted upper may be advantageously held in various positions on the anvil, to cause the formation of orifices in any desired part or parts thereof, opposite marginal portions of the upper being bent downward b the operators hands and securely eon ned during the punching operation.

The platen may be reciprocated by any suitable mechanism. The preferred mechanism includes a driving shaft 31 (Figure 3) jourualed i-n bearings on the frame and provided with an eccentric 32, an eccentric link 33, having a ring 34 embracing the eccentric, and a pair of toggle members 35, pivotally jointed to each other and to the eccentric link 33 at 36, the lower toggle member being jointed at 37 to the platen-carrying slide 15, while the upper toggle member is jointed at 38 to a pressure-adjusting block 39. Said block is adjustable on an inclined internal guiding face 40, on the frame, and may be adjusted outward or inward from the position shown by Figure 3, by an adjusting screw 41, engaged with a tapped orifice in the block. The screw is provided with an unthreaded outer portion 42, having a pcripheral groove 43, and a hand wheel 44.

A fixed plate 45 on theframc, has a slot 4.6,

the closed end of which engages the groove 43, and prevents endwise movement of the. adjusting screw when the latter is rotated. \Vhen the adjusting screw is turned, it causes an endwise movement of the block This movement is caused by the inclination of the guiding face 40, to slightly raise or lower the pivot 38, and thus slightly vary the throw of the platen, so that the degree of pressure of the platen on the punches may be minutely regulated, without moving the platen edgewise and shifting it from its predetermined path. The adjusting screw 41 is provided with a reduced extension 47, having a nut 48, constituting an adjustable abutment for a spring 49, adapted to exert endwise pressure on the screw and hold the outer edge of the groove 43 in contact with the plate 45, the object being to compensate for wear of the outer edge of the groove.

The machine may be provided with any suitable means for feeding the usual paper facing strip 50 across the acting face of the platen, said means, in this instance, including a corrugated feed roll 51, journaled in bearings on the frame and rotated step by step by any suitable connections between the roll and the driving shaft 31, and an idle.

corrugated top roll 52, pressed by springs 53 against one side of the used portion of the facing strip passing from the platen between the rolls. The facing strip is originally wound to form a sup ly roll 50 fromwhich the unused portion 0 the strip unwinds and passes over suitable guides to and across the nlatcn. The used portion passing from the feed rolls is gradually accumulated in the form of a rewound roll 50*.

I provide thehnaehine with an adjunct, adapted to loosely support and permit the unwinding of the strip from the supply roll 50, and to cooperate with the driving shaft 31 in winding the used portion to form the roll 50" and guide the strip in it's progressive movement. Said ad unct shown by Figures 4 and 5, comprises a fixed standard 55, located behind the machine, a spindle 56, fixed to the standard at 57 and projecting laterally therefrom, and adapted to support the supply roll 50, a winding shaft 58, journaled in a bearing 59 in the standard, and having a pulley 60, connected by a driving belt 61 with a pulley on the driving shaft, a pair of collars 61, adjustably secured by set screws 62 to the windin shaft and provided with fingers 63, adapte to engage the free end of the used portion of the facing strip, and a pair of elongated guiding arms 64, adjusta ly secured by set screws 65 tothe spindle 56. Said arms bear loosely on the collars 61, and are confined laterally by the shoulders 62 thereof, as indicated by Figures 5, 6 and 7. The guiding arms bear on opposite ends of the supply roll 50, and on opposite ends of the rewound roll 50 to prevent endwise displacement of said rolls. The rotation of the winding shaft causes the formation of the roll 50 thereon.

It will be seen that the bed and anvil are characterized by the fact that each is provided with a single internal or centrally arranged track or guide element, said elements being interengaged at the longitudinal central portion of the bed and anvil, so that the bed, provided with the internal guide element 21, is adapted to cooperate with either of a plurality of anvils, each having a complemental guide element 22, without change or adaptation of the guide elements. In other words, the bed having the internal centrally arranged guide or track element 21, is adapted to support and guide a rela tively narrow anvil, as shown by Figure 1, or a wider anvil, as shown by Figure 2, each anvil having a complemental centrally arranged internal guide element 22.

The substitution of one anvil for another requires no change or modification of the guide elements. It is my practice to provide with each machine a plurality of interchangeable anvils, each equipped with a die block 18, having suitable punches and the usual parts cooperating therewith, each anvil differing from the others in the form and arrangement of its punches, and each having an internal centrally arranged guide element 22. The machine is therefore adapted to be quickly and conveniently altered to enable it to produce difi'erent designs, and ornament uppers of different sizes and styles, by the simple operation of removing the anvil and substituting another therefor, without change or adaptation of the guide elements.

To prevent the possibility of injury to the cutting edges of the punches by contact with the metal of the platen, in case the punches cut entirely through the facing strip 50, I provide the platen with a non-metallic facing layer 67, preferably of dense fibrous material, such as vulcanized fiber. The facing layer may be attached to the platen by suitable means, such as screws inserted in its corner portions and engaged with tapped orifices in the platen, so that the la er is removable and renewable. The facing layer composed of material which is softer than that of the punches, contact between the punches and the relatively hard material of the body of the platen, in case the platen is improperly adjusted, so that the punches pass entirel' through the facing strip 50, a proper ad justment of the platen being one which causes the punches to only partly penetrate the strip 50.

The forward ends of the hand guards 24 are located outside the path of the plunger. The guards face downward and are extended inward from their forward ends sufiiciently to protect the operators fingers when the anvil is in difi'erent operative positions. The means for adjustably supporting the hand guards may include inner shanks 25 (Figure 4), formed on the guards and having studs 25 slidable in the fixed ears 29.

I believe myself to be the first to provide for use in a perforating or cutting-out machine an element comprising a die-block equipped with the usual punches or cuttingout dies, and the usual accessories including a stripper plate, and an individual anvil to which the die-block is fixed, the anvil being provided with a centrally or medially located guide element adapted to be movably and separably engaged with a fixed complemental centrally located guide element on the frame of the machine, so that the machine may be adapted to perform different kinds of work by removing an anvil, the dieblock of which has punches adapted to produce a given ornamentation, and substituting therefor another anvil carrying a differently formed die-block.
